香椿容器育苗基质消毒试验研究

Toona sinensis Seedling Container Matrix Disinfection Test Analysis

在温棚内培育香椿容器苗,秋季播种、移栽,人为控制温湿度,苗木在温棚内越冬生长,次年春季出圃时随机抽样调查苗木病虫害株数,用似然比x2检验法对消毒处理组调查数据进行分析,用行×列表资料的x2检验法对消毒处理组与对照组数据进行分析。6个消毒处理组间苗木病虫害率无显著性差异,消毒处理组与对照组之间苗木病虫害率具极著性差异。香椿两段式容器育苗的病虫害综合防治措施有技术上的突破,防治效果显著。

In greenhouse cultivation of container seedlings of Toona sinensis, Autumn sowing, transplanting, artificially control the temperature and humidity in Greenhouse in winter, seedling growth, spring garden when a random sampling investigation seedling pest plants, Using the likelihood ratio of x2 test method on disinfection treatment group survey data analysis, In line x list data x2 test method on disinfection treatment analysis. Result.. 6 disinfection treatment group seedling pest rate had no significant difference, group and the control group of data Disinfection treatment group and the control group between seed- ling diseases and insect pests with extremely the difference rate. Toon two of domestic, section type container seedling diseases and insect pests prevention and cure measures have the breakthrough on the technology, Significant effects of prevention and treatment.
